Throwing codes p0446 p0466 p0608 and p1416 (twice). The speedometer just quit working as well. Ours isn't one they flagged as a problem and extended the warranty on. Where do wr start without spending a crazy amount of money on mechanics

Check for a bad gas cap and make sure to tighten 3 clicks. Check to see if evap cannister purge avlave is working and you need to have secondary air system checked on rh bank, it could be clogged or a valve bad onit. What engien is this as you may not have it.
